The Napoleon Avenue electric substation, which is located on the Mississippi River near Napoleon Avenue, was knocked offline, causing outages from the Pontchartain Expressway to Audubon Park, and from Claiborne Avenue to the river.

With the electricity out, some businesses such as the Whole Foods grocery store on Magazine Street, were forced to close.

Entergy originally said that all customers would see their power restored by 8 p.m., but by 5 p.m., only a few hundred customers remained without electricity.
